Abstract

Titanium based dental material, Ti6Al4V, was covered with a thin hydroxyapatite layer using a sol gel deposition method. The research follows some coating properties and analyzes the thermal conductive behavior of the substrate and the substrate-layer materials. The substrate was prepared through different chemical procedures to increase the substrate – layer adhesion. Having a continuous and smooth character the coating presents some cracked areas and few micrometer exfoliations that are analyzed as well. Scanning electrons microscopy and X-ray analyses was used to characterize some layer properties and thermal conductivity was determined with TCi equipment..
